can't remove crankcase pulley bolt

[masonryteach]

trying to replace timeing belt on 94 honda civec ex but cant get crankcase pulley bolt off. is this bolt reverse threaded? can anyone give me advice on getting this bolt off?

[wiseguy01]

the bolt is not reverse threaded u have to use an impact gun with at least 100psi and hit it three or four times disconnect main motor mount to lower motor and use a floor jack to lower the motor and then u can impact it.. but when u go to put it on make sure not to impact it too hard because u can spin the pulley on the belt good luck

[Greenblurr93]

no need to lower the motor... i reach mine perfectly... and all you need is a 700ft/lb impact gun and a compresor will 120psi in the line.. it wont stand a chance.. however DONT use that gun to put it back on.. itll never come off.. i use a smaller, shitty impact with about the spec torque rating on the bolt and it goes right on.

[wiseguy01]

i find it easier because the timing belt is more exposed and when u have big hands u need all the room u can get

I drove my car to a neighborhood mechanic, had him zap it off then put it back on, not so tight. Charged me $20

And while we're on the subject, my timming belt seems to have some slack on the front side. i replaced the tensioner and all, could the slack come from not properly aligning the TDC marks on the cam and crank?

completely normal if u did everything right as long as one side has tension

[Greenblurr93]

a little slack is ok on the front side... did you remember to turn the crank 3 teeth bacward after you set the backside tension? that will eliminate most of your slack.

Yeah, Three Teeth Couter Clockwise. Thanks Guys.

would a huge fucking breaker bar work to get the nut off? i dont have an impact gun....

[wiseguy01]

no it will not because u are relying on the torque of the impact gun to take the bolt out if u use a bar ur just gna turn the pulley and the timing belt wont move hence timing reset and it still wont work so air compressed impact only man

[Greenblurr93]

Depending on how tight it is... if you put the car in 1st gear, and have a friend press the brakes... then take a braker bar with a long extension... rest the end of the extension on a jack stand to steady it... it MIGHT come off that way

[ThiRteeN]

Oh, cuz i saw that u get one of those strap things to keep the pully in place while u use a breaker bar.....but if i can find one ill use a gun...

[thefooshmeister]

i got one of those strap things from jegs cuz i dont have an impact..mines a little different looks kind of like a coilover adjuster..goes onto the flywheel to hold it in place..biggest waste of money..it bent trying to hold it..but i had my motor out of the car so i could lever against the crank..but it can be taken off without an impact..but if the motors in the car id definately do it to save yourself a headache..

I was told this crankcase bolt on my 1999 Honda CRV is reverse threaded. Is it true?

Honda sells a tool that holds the pulley in place for those that have no access to air tools, looks something like this:

Alot of companies make them actually. Although you'll never use it more than a couple times.
Air tools on the other hand...
